Stephenson said: "If no one can understand what they're saying, then there's a problem. I think actors not being clear is one part of it, but my understanding about the complaints about Jamaica Inn was more complex than that, so I think it's probably not right to just single out that.

"Of course we want [actors] to give brilliant performances and you've got to respect that, but if no one can understand what they're saying, then there's a problem."

Challis - who played Boycie on the legendary BBC sitcom - posted: "Jamaica Inn LOOKS very good but I haven't heard a single word that's been said. Either the actors are mumbling or the sound track is faulty."

Al - otherwise known as The Pub Landlord - joked: "Find out what happens next in Jamaica Inn by getting your ears syringed."
